Yes. You get a written scope and a fixed quote before work starts. No hourly meter and no surprise invoices.

Should I build custom software or keep buying SaaS?

Keep SaaS while it fits. Custom makes sense when you pay for several tools that don't talk to each other and people copy data between them by hand every day.

Custom software for delivery businesses, from the order to the P&L

We build one operating system for delivery retail: orders from every marketplace, the website and the app land in one queue, AI answers customers, drivers get jobs in their own app, and every order updates sales, stock, purchasing, payroll and the P&L. It replaces separate dashboards and spreadsheets.

What it does

One order queue for every marketplace, the website and the app
POS for each store
A driver app: accept, pick up, route, delivered
Payroll counted from shifts, inventory and purchasing drafts
AI that texts and answers calls for customers
One owner dashboard: sales, stock, payroll and the P&L

In production: Kamui, in production

Kamui runs a delivery retail chain: POS, every marketplace, drivers, payroll, calls and texts. It replaced a separate POS in every store, logging into each marketplace by hand, dispatching drivers by text and payroll in spreadsheets.
